Note 2 — INTRODUCTION.
Reading edition
As this Patent, in so far as the simple Kaleidoscope is concerned, was to a great extent infringed, it has been supposed that it was reduced in a Court of Law. The validity of the Patent was never questioned by any lawyer, or any philosopher acquainted with its theory and construction, as will appear from the opinion of four competent judges, given in the Appendix.
In a trial for the infringement of a Patent several years ago, a distinguished judge (we believe it was Judge Alderson) stated it as a fact, that the Patent for the Kaleidoscope had been set aside in a Court of Law. The party whose case was prejudiced by this erroneous assertion, applied to me for an affidavit, by which he was enabled to contradict it in Court, and remove any unfavourable impression it might have made upon the jury.
